Abstract
793,155. Retractive switches. GENERAL ELECTRIC CO. Sept. 11, 1956 [Sept. 19, 1955], No. 27764/56. Class 38 (5). A retractive switch has an operating bar carrying the movable contacts so arranged that they can be reversed to provide either a normally-open or a normally-closed arrangement. A base 11 and a guide member 21 are joined to terminal brackets 13 by screws 16, 26. The fixed contacts are also held by the screws 26. The guide member 21 has an aperture 28 and two legs extending downward and connected by a cross-piece 29 having a slot formed therein. A slotted channel-shaped member 30 fits over the cross-piece 29 to retain the foot of the operating-bar 32 in the slot. A compressionspring 38 is held between the member 30 and a stop 35 which clips around the bar 32. A spring 34 urges the moving contact bridge 33 against the fixed contacts 22a, 22b. When the bar 32 is depressed a stop portion 36 thereof engages the bridge 33 to open the contacts, a projection 40 first tilting the contacts. The spring 38 can be compressed so as to allow the member 30 to be lifted and then the bar and contact assembly can be removed, the side of aperture 28 being chamfered to allow this. The spring 38 and member 30 can then be placed over the other end of the bar 32 and the whole replaced in the position shown in Fig. 5 to make a normally-open switch. In both forms a well 41 arrests the downward movement of the bar 32.
